Cause mine is seriously dark. It works, but it's like it should be backlit and isn't. Can it be popped out and is there a bulb back there I can replace? The rest of the dash is nice and bright, but not the OBC. I'm just wondering if it's SUPPOSED to be as bright as the rest of the dash.
Thanks!
-
yes it has 2 bulbs in the back and they should be bright but rarely are
-
Cool can they be replaced? I'll check it out. My cluster bulbs were all out, as well as the side headliner lamps, and the glovebox lamp, so I imagine these are too. The PO didn't like changing bulbs apparently!

Here's the light bar on eBay (http://cgi.ebay.com/ebaymotors/BMW-OBC-Light-Bar-E30-325i-325-1987-1991_W0QQcmdZViewItemQQ_trkparmsZ72Q3a552Q7c39Q3a1Q7c65Q3a12QQ_trksidZp3286Q2ec0Q2em14QQhashZitem310059488911QQitemZ310059488911). You could also take the bulbs that are burned out to the dealer. They should have them all in stock...

That light bar does not fit in our 6 button OBC's...Ours takes 2 bulbs that are in separate "turn and lock" bulb holders.

:o You are right. oops

Mine is dim as well....should it be brighter when you turn the headlights on?

The heater controls, the gauges, the OBC should all light up when you pull your light knob.

I have found that my local Pep Boys auto parts store carries all of the bulbs needed for the interior of BMW's... even the really tiny bulbs that are located within the OBC's, the front ashtray and rear ashtray...
:)

I just replaced the two bulbs and it looks like it should...bright as hell!

Very nice! maybe ill do this today! where and how much did you get your bulbs? Does the 13 Button take the same bulbs i wonder.
-
I am not sure about the 13 button OBC, but I just ordered the two bulbs from RMEuropean....I guess you could check Pep Boys to see if they have them. Then you don't have to wait for shipping. They are the little 12 x 1.5v I believe

The LED display is lit by a white plastic lightbar with two bulbs soldered onto it. There is one twist-on bulb to illuminate the buttons that is identical to the six-button OBC.

There is a little hole-looking thing on the front of the clock that varies how bright the backlight gets.
-
Do these tiny bulbs come out of the black casing or is it one piece?

These are the one-piece kind - sort of like a christmas light bulb. There are other bulbs in the dash that are sockets and the bulbs themselves can be replaced.

I think they just slide out with that little white bit on the side...I'm currently swapping a 6-button for the 13, guess I should have checked.
-
Hey Dave what are you doing with the 6 button.......:rolleyes:??

I've got a couple extras - if you want one send me a pm.

My 13-button isn't lighting...I must have trimmed off too many wires, or the bulbs are burned out.
Does anyone know offhand which wires should go to the 13 button besides the ones from the cluster?

Are you doing custom wiring? The only wires going to the OBC should all be in one bundle with one green plug.

No custom wiring...I pulled the harness from a parts car and trimmed the extra relay wires off. It's now only the ten or so wires going between the yellow and green connector.
-
I think you may need some of the wires that run down to the power distribution box on the left side of the steering column beneath the dash. If I recall correctly that is where the light gets its power from. Check the electrical troubleshooting manual - I don't think it has the 13OBC wiring but the 6-button wiring should be similar.

Yeah...I'm sure you're right. It'll have to wait for some serious spare time...I have to chase down a leak into the driver's footwell anyway; might as well add the 13-button to the cruise control & do it all at once...
I just had a though...the 6-button has wires running off somewhere else...I'll bet they're similar. I'll be matching up some colors and post results!

How'd your cruise control and OBC upgrade go? I'm collecting the parts to do the same. Any gotchas? Thanks!
